Twenty-three years ago, Sam and Dean Winchester lost their mother to a demonic supernatural force. Following the tragedy, their father, John, set out to teach his boys everything about the paranormal evil that lives in the dark corners and on the back roads of America...and how to kill it.

Fans of the blockbuster television phenomenon can rejoice! A one-of-a-kind compilation of all of Sam and Dean's demon-busting knowledge, The Supernatural Book of Monsters, Spirits, Demons, and Ghouls contains illustrations and detailed descriptions that catalogue the more than two dozen otherworldly enemies that most people believe exist only in folklore, superstition, and nightmares:vampires, ghosts, revenants, reapers, and even bloody clowns. You'll find within these pages Sam and Dean's notes, observations, and memories interwoven with sections of John Winchester's invaluable journal, making this book the perfect companion to every thrilling episode—and an essential weapon in the secret war against the hidden creatures of the darkness!
